... Fatigue Evaluation Method 2022 Edition with some modifications. Also, research on effects of surface finishing and mean stress on fatigue lives of notched specimens have been followed by DFC3 and DFC4 subcommittees with supports from the Japanese utilities. In this paper, test plan and overview...

... specimens. Polished smooth specimens and notched specimens with stress concentration factors of 1.5 and 1.8 were prepared for fatigue tests. Firstly, the regression curves of both smooth and notched specimens were obtained from fully reversed fatigue tests. Secondly, mean stress fatigue tests for notched...

... of the application of the analytical method to circular notched specimens. Furthermore, the loading conditions for fatigue tests of circular notched specimens subjected mean stress were examined. The results indicated that fatigue tests with mean stress of about 5 MPa to 17 MPa and 9 MPa to 17 MPa can be expected...

... (JSME S NF1-2022). Research on the effects of surface finishing and mean stress on the fatigue lives of notched specimens were followed by DFC3 and DFC4 subcommittees. In this paper, the application of elastic-plastic Finite-Element Analysis (FEA) for fatigue evaluation of notched specimens of low alloy...

... the stress gradient calculated using FEA, and the fatigue strength reduction ratio was determined. Later, a fatigue test was conducted on a notched specimen of low-alloy steel to verify the stress-gradient approach, and the fatigue life of the notched specimen was predicted considering the stress gradient...
